Israel’s Defense Ministry began this month upgrading the “Hourglass” security fence along the Gaza Strip, the Jerusalem Post reported, based on lessons from the October 7 attack and the war against Hezbollah.

One of the five work fronts integrates technologies and methods to counter very low-altitude threats, particularly fiber-optic drones used by Hezbollah in southern Lebanon. The 64-kilometer fence had been criticized after being breached at dozens of locations.
